Thread: Transmission fluid leaking into radiator.

Replace the radiator, flush the coolant out, replace with new, drop the pan on the transmission, put in new filter and new fluid. Then have the trans flushed as soon as possible afterwards.

I could not agree more, do exactly this.

This happened on my camaro.
